SPRING-WHEEL.

Speccation of Letters Patent.

Patented Sept. 19, 1911.

To all whom t may concern:

Be it known that I, ALFRED J. SWING, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Spring-Wheels, ofwhich the following is a specification.

My invention relates to an improvement in spring wheels, wherein theyielding connections between the hub portion and rim portion areconnectedV to each other, parallel with the axis of the wheel, so as toserve for both vertically yielding and lateral strains brought betweenthe members.

The object of my invention is to provide a spring wheel, with abifurcated hub eX- tension, with the rim interposed between the same,and tension means connecting with the rim and hub extensions upon eachside thereof.

The features of my invention are more fully set forth in the descriptionof the accompanying drawings, forming a part of this specification, inwhich Figure 1 is a side elevation of my improved spring wheel. Fig. 2is a section on line caf-00, Fig. 1.

As illustrated in the drawings, the wheel is preferably formed of sheetmetal plates, stamped and bent in the proper shape and riveted orotherwise secured together.

1 represents the hub, provided with the annular flanges 2, 3, to whichare secured the web-plates 4, 5, forming a bifurcated extension of thehub.

6 represents reinforcing plates interposed between the web plates 4f, 5,to relieve the web plates of inward or bending strain.

The peripheries of the web are preferably of scalloped-formation, toprovide the hooked bends 7.

8 represents the rim, its periphery preferably of channel formation, toreceive the elastic tread band 9. The rim on its inner periphery isprovided with the web-plates 10, 11, joined together in a verticalmedial line of the rim forming a reinforced web, with its innerperiphery preferably also of scalloped-formation, to provide means, inthe form of hook bends 12, alined with the hooked bends 7, to receivethe coil springs 13, 14, upon each side of the rim web.

Thus, the lateral and vertical strains are taken care of by duplicatesprings, disposed parallel to the axis of the hub, and with the actionof each spring, upon each side of the rim web, independent of eachother. This prolongs the life of the spring, makes the wheel moreresilient, with the springs accommodating themselves to and taking careof all the strains in any direction or angle incident to its use.

While in the general construction of the wheel, stamped sheet metal isemployed, it is obvious, that the same may be otherwise built, withoutdeparting from the features of my invention.

Having described my claim l. A wheel, comprising a first membersurrounding the wheel axis at right angles to said axis and providedwith a circumferential series of radial arms, a second member similarlysurrounding the wheel axis and formed with two parts, each of the partsbeing provided with radial arms in alinement with the radial arms of thefirst member, one at each side of said first member, one of said membersbeing secured to the hub of the wheel and the other to the rim of thewheel, and a circumferential series of spring devices extending acrossbetween the two parts of said second member and having their endsattached to the radial arms of the two parts of the second member andhaving their central portions permanently attached to the radial arms ofsaid first member, combined substantially as set forth.

2.- A wheel, comprising a hub, a pair of separated disks rigidly securedthereto and lying in planes at right angles to the axis of the hub,outwardly concave bows disposed between the disks and having their outerends rigidly secured to lthe outer portions of the disks, acircumferential series of tension springs having their ends securedinvention, I

to the outer portions of said disks at the In testimony whereof, I havehereunto set outer ends of said bows, a rim` an annular my hand. inwardextension from the rim to apoint midway between the two disks, and,means for securing said annular member to the Writnesses: intermediateportion of each of said springs, EMMA SPEUER, combined substantially asset forth.
